Red is the colour of blood and nothing is dearer to us than blood. It is, literary, the colour that keeps us alive. Professor Roy Behrens of University of Northern Iowa, and founder of the Camoupedia website, agrees: “Red is intimidating. It is hot, partly because of conspicuousness. But also because it alerts us to blood, fire, passion, stop signs, and the blush of rage.”
That rage, and most other aforementioned traits, explains why red is also closely associated wit the military, believe it or not. It appears to be more of Romeo & Julia colour at first glance, but its raw and emotional energy is also why it’s equally suited for the battlefield, as well as the silver screen. And though it might seem unlikely when you picture most modern-day battle dresses, there was a time when red was the go-to colour for armies around the world.
